Question

the head of a sperm contains __________. a many organelles b a nucleus enclosing the 23 chromosomes c a large amount of cytoplasm d all apply.

Explanation:

Sperm cells are highly specialized for fertilization. The head of a sperm is mainly composed of a nucleus. The nucleus contains 23 chromosomes (haploid number, as sperm is a gamete). Sperm cells do not have many organelles in the head (most organelles like mitochondria are in the mid - piece to provide energy for motility). Also, there is not a large amount of cytoplasm in the head (cytoplasm is minimized to make the sperm more streamlined for movement).

Answer:

B. a nucleus enclosing the 23 chromosomes
